From New York to Paris, the vocal style vary

Jay-Z pronounces ‘New York’ like the New Yorker that he is, but pronounces ‘Paris’ as the French would say it: his vocal style varies.

I think the whole point of this line and the one above is that he is able to talk like a wealthy member of the upper class because of his wealth and life of luxury, but also use slang in order to represent his upbringing in Marcy.

He’s also just showing off that he goes to Paris.

He is also using the double entendre in it’s purest form — Suggesting sexual innuendo. He sticks pearl tongues from NY to Paris, the vocal style varies… He’s telling two tales, as stated in the above explanation, but connects tongues to vocals to complete the exotic/quality nature of the blowjobs he gets…
